3 Your advantages when using electromagnetic ROBATIC -clutches, ROBA -quick brakes and ROBA -takt clutch brake units Easy integration into your machine: The optimised magnetic circuit minimises the magnetic leakage flux. The high power density and torque security based on it allow compact dimensions and an easy integration in your construction. High reliability and operational safety: The switching behaviour is constant during the entire service lifetime. Therefore, the positioning accuracy and reliability of the clutches or brakes respectively and herewith the operational security of your machine are increased. Less operating expenses and maintenance charges: The large friction surface and the smooth switching behaviour increase the wear resistance. Therefore, the clutches and brakes are maintenance-free until the friction surfaces are worn down. There is no re-adjustment work and the resulting operational interruptions. Therefore, the operating expenses and maintenance charges are very low. Increase of productivity: Short switching times allow high switching frequencies and increase the productivity of your machine. Total Quality Management Product Quality Every delivery which leaves our firm has been subjected to a careful quality inspection, meaning that you are able to rely 00 % on mayr products. If required, we pre-adjust our clutches and brakes accurately to the requested values and confirm the product characteristics with an Inspection Report.

4 Electromagnetic Clutches and Brakes Guidelines Description and Operating Conditions. The catalogue values, in particular the values for the nominal torque, are reference values and may deviate in individual cases. 2. During dimensioning, please contact the manufacturers for consultation on installation conditions, torque fluctuations, permitted friction work, run-in behaviour, wear and ambient conditions. 3. The clutches and brakes are designed for dry running. If the friction surfaces come into contact with oil, grease or similar substances, there may be a severe decrease in torque. 4. When the devices are switched off, voltage peaks may occur due to the counter-induction on the magnetic coils, causing in extreme cases damage to the magnetic coil and therefore to the components. For this reason, excess voltage must be damped using a suitable protective circuit (e.g. using a varistor). 5. The surfaces on the clutches and the brakes are corrosionprotected except for the friction surfaces. However, in operation in extreme ambient conditions or in outdoor conditions with direct weather influences, additional protective measures are necessary. 6. The connection cable or connection strands on the clutches and brakes have a surface coating which is not resistant against all influences. After contact with chemical substances, please check compatibility. 7. The clutches and brakes are designed for a relative duty cycle of 00 %. Torque Characteristics In new condition, c. 50 % of the catalogue nominal torque (M 2 ) is transmitted. The components reach the catalogue nominal torque when the friction surfaces are run in. As a rough guideline value, c switchings in dynamic operation, a typical speed (c. 50 to 000 rpm) and a medium friction work (see Table ) can be given. Longer slipping of the clutch or brake is to be avoided, especially at low speeds, as this can cause scoring formation and therefore damage to the friction surfaces. Clutches or brakes used in static or virtually static operation do not reach the nominal torque (M 2 ). If requested, the clutches or brakes can also be run in at the place of manufacture. This is most expedient for Type with complete bearing. However, Types 500. and 520. can also be run in under certain conditions. For this, please ensure exact installation customer-side according to the regulations in order to reproduce the friction conditions as precisely as possible. At the same time, the friction carbon produced must not be rubbed off. If the clutch is run in to the nominal torque at the place of manufacture and then operated in static or virtually static mode, please allow for a drop to c % of the nominal torque. This is the case if the clutch or brake falls below the speed or friction work (Q a ) stated in Table. For static and virtually static applications, we therefore recommend our double-flow designs construction series (see pages 2/3). Friction work Q a [J] Clutch or brake speed n min. [rpm] Run-in Conditions For running in, different procedures can be used according to the Type design. An artificial run-in is to be carried out if a run-in procedure is not possible in the machine due to the type of application (see section Torque Characteristics ), e.g. due to insufficient friction work, speed or switching frequencies. For the run-in conditions of the individual clutch and brake types, please see the respective Installation and Operational Instructions on our website Electrical Connection and Wiring DC current is necessary for the operation of the brake. The coil voltage is indicated on the Type tag as well as on the brake body and is designed according to the DIN IEC (± 0 % tolerance). Operation is possible both via alternating voltage in connection with a rectifier or with another suitable DC supply. Dependent on the brake equipment, the connection possibilities can vary. Please follow the exact connections according to the Wiring Diagram. The manufacturer and the user must observe the applicable directives and standards (e.g. DIN EN and DIN VDE 0580). Their observance must be guaranteed and double-checked. Electrical Wiring 24 VDC and 04 VDC can be selected as standard voltages. 24 VDC: Operation with a power supply unit of 24 VDC 04 VDC: Half-wave recifier with 230 VAC mains voltages Earthing Connection The brake is designed for Protection Class I. This protection covers not only the basic insulation but also the connection of all conductive parts to the PE conductor on the fixed installation. If the basic insulation fails, no contact voltage will remain. Please carry out a standardized inspection of the PE conductor connections to all contactable metal parts. Device Fuses To protect against damage from short circuits, please add suitable device fuses to the mains cable. Protection Circuit When using DC-side switching, the coil must be protected by a suitable protective circuit according to VDE This is achieved by using a sufficiently dimensioned varistor, which has already been integrated into the mayr rectifier. To protect the switching contact from consumption when using DCside switching, additional protective measures may be necessary (e.g. series connection of switching contacts). The switching contacts used should have a minimum contact opening of 3 mm and should be suitable for inductive load switching. Please make sure on selection that the rated voltage and the rated operation current are sufficient. Depending on the application, the switching contact can also be protected by other protective circuits (e.g. mayr spark quenching units), although this may of course then alter the switching times. 4 Table

6 ROBATIC -electromagnetic clutch Constant switching performance throughout the entire service lifetime High torque security due to an optimised magnetic circuit and the new design of the ROBATIC -clutch. Therefore, higher capacities due to less magnetic leakage flux. Half the wear due to large friction surfaces and smooth switching behaviour, the ROBATIC -clutch has a higher wear resistance (approx. 00 %). Large internal diameters of the magnetic coil bodies therefore large permitted shaft diameters Low noise Short switching times/high switching frequencies Correct function up to wear limit wear, air gap max. adjusting interval conventional electromagnetic clutches number of switchings Functional principle ROBATIC -clutches are energise to engage, electromagnetic pole face units. When DC voltage is applied to the magnetic coil (), a magnetic field is build up, the armature disk (3) is attracted to the rotor (2) and the friction lining (4). The torque is transmitted via friction locking. The torque is transmitted from the drive element (6) via the armature disk (3) and the rotor (2) to the output shaft (7). After having de-energised the coil, the membrane spring (5) draws back the armature disk (3) to the drive element (e.g. belt pulley), and the torque transmission is then disconnected. wear, air gap max.

Please ensure that the shaft is fastened axially, since otherwise the dimension a will change and cause the rotor to brush against the armature disk or the coil carrier. The air gap e is selected so that a brushing of the rotor against the coil carrier is not possible when keeping to the permitted centre offsets V and V (see Table ). 22 Design: ROBATIC -electromagnetic clutches are manufactured according to the electric protection IP 54 specification and the insulation material class F up to 55 C for coil, moulding compound and connection strands as well as insulation class B +30 C for the magnetic coil plastic-coated. The friction linings are asbestos-free, the surfaces of coil carrier, rotor and flange hub are phosphated. The armature disk is gas nitro-carburized and the transmission spring is made of stainless steel. The drive elements should be made of magnetically poorly transmitting material to avoid magnetic leakage flux and subsequent power reduction. ROBATIC -electromagnetic clutches are used for dry running. The torque is transmitted via the connection of the armature disk on the iron poles and the friction lining of the rotor (except the double-flow ROBATIC clutch without friction lining, Type _.0). When coupling two shafts, the eccentricity V of the shafts according to Table 2 must not be exceeded. The larger the misalignment V the more the torque decreases and the hotter the friction surface becomes. In the case of this arrangement care must be taken that both shafts have no axial backlash since, otherwise, a brushing of the rotor would also be possible. The flange hub is kept axially by means of a set screw (on set 90 to the key). The V -values are indicated again in the Technical Data of the individual clutches. Please observe: The run-in conditions or the minimum speed must be observed (see page 4). The friction surfaces have to be absolutely free of oil and grease, as otherwise, the torque drops significantly. The air gap a (Fig. ) has to be checked periodically. The clutch does not function correctly, if the max. working air gap is exceeded (see Table 4, page 25). Assembly and maintenance should be carried out by well trained specialists.

Please ensure that the shaft is fastened axially, since otherwise the dimension a will change and cause the armature disk to band against coil carrier. Design: ROBA -quick electromagnetic brakes are manufactured according to the electric protection IP 54 specification and the insulation material class F up to 55 C for coil, moulding compound and connection strands as well as insulation class B +30 C for the magnetic coil plastic-coated. The friction linings are asbestos-free, the surfaces of coil carrier and flange hub are phosphated. The armature disk is gas nitro-carburized and the transmission spring is made of stainless steel. ROBA -quick electromagnetic brakes are used for dry running. The torque is transmitted by friction between armature disk and the iron poles and the friction lining surfaces of the coil carrier. When braking the eccentricity V according to Table must not be exceeded. The larger the displacement V the more the torque decreases and the hotter the friction surface becomes. In the case of arrangement according to table care must be taken that the coil carrier and shaft have no axial backlash since otherwise a brushing of the coil carrier would be possible. The flange hub is kept axially by means of a set screw (on set 90 to the key). The V -values are indicated again in the Technical Data of the individual brakes. Please observe: The run-in conditions or the min. speed must be observed (see page 4). The friction surfaces have to be absolutely free of oil and grease as otherwise, the torque drops significantly. The air gap a (Fig. ) has to be checked periodically. The brake does not function correctly if the max. working air gap (see Table 4, page 39) is exceeded. Assembly and maintenance have to be carried out by well-trained specialists. 36

52 Technical Explanations ROBA -takt clutch brake module Installation Clutch Brake Unit with flange: The shafts, centring, screw-on pitch circles and diameters of the flanges are designed according to IEC-standard. Input and output sides can be fitted with the corresponding flanges of motor, gearbox or other units without problems, as shown in Fig.. Permitted shaft loads The drive elements located on the shafts exert a radial load during operation which has to be absorbed by the bearings of the unit. The load is limited by the required life of the bearings and strength of the shaft (Table ). Fig. 3 Fig. Installation of the transmission elements: The drive elements are mounted onto the respective shafts and secured axially via a press cover and a screw screwed into the threaded centre hole of the shaft, see Fig. 2. For the combination motor shaft - ROBA -takt hollow shaft, the motor shaft must be greased slightly to prevent frictional corrosion. Extensive force or hammer blows can damage the bearings. Radial loads acting on the shaft via the drive elements must not exceed the maximum allowable values (see heading permissible shaft load ). Should both radial and axial loads be present on the shaft, the permissible loads must be determined - please contact our engineers.

56 ROBA -takt control unit Type Application This unit is used to start, stop and to position by switching and controlling the mayr ROBA -takt clutch brake modules. Function The ROBA -takt control unit operates according to the principle of a clocked switching controller with a frequency of 8 khz. Its coil is energised by actuating the sensor for clutch and brake. A temperature monitor protects the unit from overheating. Should the temperature exceed >80 C, the coil voltage is switched off. The LED excess temperature unit lights up red. A slope separation avoids simultaneous occurrence of clutch and brake torques. On overexcitation, the coil attraction time is reduced, allowing exact switching and positioning.

58 Application This device is used to start and stop mayr ROBA -takt clutch brake modules. It can be used for alternating 24 VDC coil switching, if a 24 VDC power supply is available. ROBA -takt circuit module Type _ Function -sensor operation: activated deactivated clutch is energised brake is energised The respective control of the clutch or brake is indicated via LED. The ROBA -takt circuit module has no over excitation function. The brake has priority: The brake is energised independently of the sensor position when the 24 VDC power supply is switched on. The coil is energised with the 24 VDC power supply. Slope separation: To avoid simultaneous clutch and braking torques, a slope separation of 0-00 ms between clutch and brake can be set, which acts according to the respective rise time and drop-out time of the coils (see switching time table). This adjustment is carried out via the potentiometers Ku clutch (P2) and Br brake (P). The factory default setting is 0 ms.
